-x is not considered to be an expression.
As an algebraic expression it is simply: 18-x
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
The expression (x+5)(x-7) = x^2 -2x -35
Expression.
Yes, -6+x is the same as x-6.
The important thing to note is that multiplication is just repeated addition. Thus nine x can be written as x+x+x+x+x+x+x+x+x. And we want to add another x onto the end of that. This can then be simplified back to the multiplication 10x. Therefore an equivalent expression to 9x+x is 10x
i was just wondering the same thing...
If the algebraic expression can be written in the form of a(x)/b(x) where a(x) and b(x) are polynomial functions of x and b(x) ≠0, then the expression is a rational algebraic expression.
The expression is: x/2
As an algebraic expression it is simply: 18-x
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.

It is an expression with a variable, x.It is an expression with a variable, x.It is an expression with a variable, x.It is an expression with a variable, x.
As an algebraic expression it is: 9-x
The expression is: x² + 2
That expression is x-6.
Let the unknown number be x and so the expression is: x+12
